问题描述

if(checkBox1.Checked==true && checkBox2.Checked==true)
            {
**// check box1 statemet//**
                DataSet ds = new DataSet();
                ds.Clear();
                SqlDataAdapter da = new SqlDataAdapter("select sum(amount) from addtransaction where transactiontype='income'", con);
                da.Fill(ds);
                richTextBox2.Text = "Total Income :  " + ds.Tables[0].Rows[0][0].ToString();

                DataSet ds1 = new DataSet();
                ds1.Clear();
                SqlDataAdapter da1 = new SqlDataAdapter("select sum(amount) from addtransaction where transactiontype='Expense'", con);
                da1.Fill(ds1);

推荐答案

为什么要打破？如果您不想执行第二个块代码，则将其添加到else块中。

Why do want to break? If you do not want to execute the second block code then add it in the else block.

if(checkBox1.Checked==true  )
 {
 **// check box1 statemet//**
 DataSet ds = new DataSet();
 ds.Clear();
 SqlDataAdapter da = new SqlDataAdapter("select sum(amount) from addtransaction where transactiontype='income'", con);
 da.Fill(ds);
 richTextBox2.Text = "Total Income : " + ds.Tables[0].Rows[0][0].ToString();
}
else if(checkBox2.Checked==true)
{ 
  
 **//check box2 statemet//**

 DataSet ds1 = new DataSet();
 ds1.Clear();
 SqlDataAdapter da1 = new SqlDataAdapter("select sum(amount) from addtransaction where transactiontype='Expense'", con);
 da1.Fill(ds1);
 richTextBox2.Text = "Total Expense : " + ds1.Tables[0].Rows[0][0].ToString(); 
}
